NAIROBI, Kenya — An American diplomat who police say was speeding crossed the center line in his SUV and rammed into a full mini-bus, killing a father of three whose widow is six months pregnant, officials said Friday.

U.S. Embassy officials in Nairobi rushed the American and his family out of Kenya the next day, leaving the crash victims with no financial assistance to pay for a funeral and for hospital bills for the eight or so others who were seriously injured.
